Create an Azure Cosmos DB for Gremlin account, database and graph using Azure CLI

APPLIES TO: Gremlin

The script in this article demonstrates creating a Gremlin database and graph.

If you don't have an Azure trail subscription, create a trial subscription before you begin.

Prerequisites

You can use the local Azure CLI.

  • This article requires version 2.30 or later. Run az --version to find the version. If you need to install or upgrade, see Install Azure CLI. If using Azure local Shell, the latest version is already installed.

    Note

    Before you can use Azure CLI in Microsoft Azure operated by 21Vianet, please run az cloud set -n AzureChinaCloud first to change the cloud environment. If you want to switch back to Azure Public Cloud, run az cloud set -n AzureCloud again.

Sample script

Sign in to Azure

Use the following script to sign in using a different subscription, replacing <Subscription ID> with your Azure Subscription ID. If you don't have an Azure trail subscription, create a trial subscription before you begin.

az cloud set -n AzureChinaCloud
az login

subscription="<subscriptionId>" # add subscription here

az account set -s $subscription # ...or use 'az login'

For more information, see set active subscription or log in.

Run the script

# Create a Gremlin database and graph

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="chinaeast2"
failoverLocation="chinanorth2"
resourceGroup="msdocs-cosmosdb-rg-$randomIdentifier"
tag="create-gremlin-cosmosdb"
account="msdocs-account-cosmos-$randomIdentifier" #needs to be lower case
database="msdocs-db-gremlin-cosmos"
graph="msdocs-graph1-gremlin-cosmos"

# Create a resource group
echo "Creating $resourceGroup in $location..."
az group create --name $resourceGroup --location "$location" --tags $tag

# Create a Cosmos account for Gremlin API
echo "Creating $account"
az cosmosdb create --name $account --resource-group $resourceGroup --capabilities EnableGremlin --default-consistency-level Eventual --locations regionName="$location" failoverPriority=0 isZoneRedundant=False --locations regionName="$failoverLocation" failoverPriority=1 isZoneRedundant=False

# Create a Gremlin database
echo "Creating $database with $account"
az cosmosdb gremlin database create --account-name $account --resource-group $resourceGroup --name $database

# Define the index policy for the graph, include spatial and composite indexes
printf ' 
{
    "indexingMode": "consistent", 
    "includedPaths": [
        {"path": "/*"}
    ],
    "excludedPaths": [
        { "path": "/headquarters/employees/?"}
    ],
    "spatialIndexes": [
        {"path": "/*", "types": ["Point"]}
    ],
    "compositeIndexes":[
        [
            { "path":"/name", "order":"ascending" },
            { "path":"/age", "order":"descending" }
        ]
    ]
}' > "idxpolicy-$randomIdentifier.json"

# Create a Gremlin graph
echo "Creating $graph"
az cosmosdb gremlin graph create --account-name $account --resource-group $resourceGroup --database-name $database --name $graph -p "/zipcode" --throughput 400 --idx @idxpolicy-$randomIdentifier.json

# Clean up temporary index policy file
rm -f "idxpolicy-$randomIdentifier.json"

Clean up resources

Use the following command to remove the resource group and all resources associated with it using the az group delete command - unless you have an ongoing need for these resources. Some of these resources may take a while to create, as well as to delete.

az group delete --name $resourceGroup

Sample reference

This script uses the following commands. Each command in the table links to command specific documentation.

Command Notes
az group create Creates a resource group in which all resources are stored.
az cosmosdb create Creates an Azure Cosmos DB account.
az cosmosdb gremlin database create Creates an Azure Cosmos DB for Gremlin database.
az cosmosdb gremlin graph create Creates an Azure Cosmos DB for Gremlin graph.
az group delete Deletes a resource group including all nested resources.
